## GDB LOCAL
## Don't mess with people's installed readline's.
## This tries to install this version of readline over whatever
## version is already installed on the system (which could be a
## newer version). There is no real reason for us to install
## readline along with GDB. GDB links statically against readline,
## so it doesn't depend on us installing it on the system.
